for Mak the following is a specification.

This invention aims to provide a machine for assembling blocks ofmarble, ceramic,

ing floors. The blocks, of whatever material I designate generically asmosaic, are fed in successive transverse rows or in adjacentlongitudinal lines, preferof a long narrow ably a fabric in the formstrip, which fabricserves as a holder for the other foundation of thefloor, the fabric being removed after the blocks are laid in place. Bythe use of the machine described the sections of assembled blocks can bepractically any size and with great rapidity, and the laying of thefloor from such large sections can be accomplished much more rapidlythan by present hand rocesses. Also the blocks may be assemble directlyon the floor.

The accom anying drawings illustrate machines embodying the invention.

A strip of pper or similar fabric F is drawn continuously rom a roll f and is coatedocks are, inverted at the en of the conveyer or belt E and are broughtwith their faces .uponthe' adhesive face of the fabric F. Th strip isthen carried forward and woun upon around the roller H and at the sametime to hold the blocks upon the fabric until the I have perfectlyadhered thereto, a stri of fe t or canvas J is wound around with t ecompound fabric, pressing against the exposed backs of the blocks. a

The paper strip, with the blocks thereon, is then transportedto the may be inverted upon or other foundation adjusted into place,after which the paper may be removed by Wetting it. For convenience intransporting the com ound st'ri it may be wound on a second roli as thefe t or canvas is Withdrawn. Each of the chutes D'is substantially theWidth of one .block, leaving only sufficient play to permit a block toslide down freely.

The chutes are close to each other at their lowerends, but are spreadper ends to locks apart at their ulpfacilitate the entrance of t ethereinto. Considerable difficulty and quickly has been found inavoiding the jamming off the blocks at the mouths of the chutes.

This difliculty hasbeen minimized'bly) sepa;

rating-the mouths, as explained, and

viding between the mouths of each two adjacent chutes a triangular guideK, which is tapered downward at the sides, as indicated in Fig. 7. Whentwo blocks attempt to en ter the mouth of the same chute at the sametime, one of them will be gradually forced up the tapered side of theadjacent guide'K and out of'the way, permitting the other to pass freeand clear into thechute.

The chutes D are mounted seats to permit a slight movement at the pointsof connection of their upper and lower ends with the tray and with thelower conveyor E,respectively, so as to permit a lateral shaking orjogging of the trayf). The blocks are dumped in all positions on thetray, and means are provided for shaking the tray laterally andpreferably, also, for bumping it up and down, each of these movementsbeing comparatively slight in amplitude, but sudden. The result is thethrowing down of such blocks as originally stood on edge and the gradualfeeding or the blocks down the inclined tray. The floor of the tray isunobstructed, so as to permit these operations. It is preferable thatthe tray shall not be steeply inclined, so as to exert a considerablepressure from the blocks therein upon those which are entering themouths of the chutes or are within the chutes, and the shaking andbumping movements referred to feed the blocks forward with very littlepressure from the blocks behind them.

' the tray and contents.

Various mechanical arrangements may be provided. 'for securing themovements described. ln'l igs. 6 and 7- means are illustrated. for thispurpose. The tray (3 is supported and guided upon. a pair of cross-rodsI] and is connected to a lever M, which is ese'i llated by an eccentricNon a continuouslyrotatipg shaft O, running alongside of the machine.Rubber or spring bufii'ers P are arranged atlhe sides, being mounted onthe ends of adjustable bolts Q. As the tray is thrown ,to one side orthe other by the swing ing of the lever -M it strikes at the end of itsthrow against the buffers P, which give it a sudden bump or return. Inthe middle of its transverse movement a projection E, Fig. 7, on theunder side of its tront edge strikes an adjustable projection S upon asuitable fixed. portion of the frame and rides over said projection,thus giving a slight vertical bump to The action is quick, so that thetray is practically in a constant state of agitation vertically andlaterally.

The blocks are brought to the tray 0 and i dumped therein by means of abucket elevator or conveyer B. The upper shaft T of the canveyer ismounted u on the frame which 7 carries the tray and is riven by a beltand pulley on the shaft 0.

gate U, swinging horizontally. The free end of the gate U is connectedto a spring V, pulling it The lower end of theconveyer is mounted underthe hopper A, and the latter is provided with a G, an endless band 9 inthe closing direction, while a cord W runs to the lower end of the leverM to pull the gate in the opening direction as the lower end of thelever M swings outward. In "order to feed the blocks to thetray inexactly the quantity desired, so as to neither overflow norrun short,the amount of opening of the gate is adjustable by a take-up inserted inthe cord W. in the illustration shown a roller X engages the bight ofthe cord N and is carried upon a lever Y, the free end of which isconnected to an adjusting-wheel Z at the opposite side of the machine.For a given position of the gate-operating lever M the gate will be moreor less open the roller X is a greater or less distance from. theoperatingdever. 1

From the lower end of the individual chutes D the blocks are assembledupon a beltrunning over a platform or support a, along which they areconveyed by the belt E. It will be seen that the blocks are exposed inthe tray and in the individual chutes, so that the operator may therecorrect any imperfections. It is preferable, however, to do this upon asubstantially horizontal sup port, where the blocks may be arranged witha slight degree otloosene. and will not press against each other, andfor this purpose the support (1. may be made of suliicient length togive ample time for the correction of imperfections, the length, ofcourse, depending upon the speed of operation. After being exposed forinspection upon the support a the blocks are applied to the paper stripwith their faces against the adherent side of the strip. in the machineshown in Figs. .l to 7 this is accomplished by inverting the blocks atthe end oi the support. The belt E trav els at its discharge end over aroller 6, and a hood. 0 is provided, fitting close enough to the facesof the blocks to hold. them in. place. At the lower end of the hood is apivoted chute or tray cl, the lower end of which rests upon or directlyabove the paper, so as to fit the now inverted blocks upon the paper.The pivotal arrangement pern'iits the lower end of the tray to move asthe size of the roll upon the roller ll varies, so that the feed fromthe free end oi the tray shall always be approximately tangential. Theblocks being fed in a somewhat loose condition to the chute d arelightly packed together thereon in the longitudinal direction by theweight of the blocks and in the transverse direction by a pair of flatsprings Fig. 2.

The strip oi paper 1* is drawn from a roll f and after passing oversuitable tension-rollers receives a coat of adhesive from the pot beingarranged to run through the liquid adhesive and over the face of thepaper F. The paper maybe supported upon an apron 71. adjacent to thepoint where it receives the blocks. If the composite strip 1S wound uponthe roller H, it takes an arched IIC I slightly upon the adherent a beltit drives the shaft O,'wh1ch opposite end.-

'tated forwhr 31 transmits ,pu ta ly proportioned to form, with the paer on the inside, which creates diflicul'ties W en it is attempted todraw it ofi the roll in a straight line. Therefore it is preferable torun it first under a supplementary roll 7', which bends it in the 0 0-site direction and, in effect, s reads theblocks ace of the p Thereafterwhen the composite strip is wound on the main roll H it is wound withthe blocks spaced from each other slightly, but to such an extent as topermit the easy unrollin of the com osite strip in a straight line. ater the bloc s become fixed on t e paper. The felt or canvas J, which iswound on the roll H with the composite strip, is drawn from'a roller kand over a guide roller Z to en age the blocks at or near the top of therollerT-I;

Various arrangements may be ado ted for driving the several parts of themec anism. In the mac 'ne shown the ower is taken from an overhead shaftm. rom this shaft -o erates the mechanism at the right-hand en he inFigs. 1 and 3. shifts the belt 'n, from a fast to'a loose ulley o 0 onthe shaft 0, as desired. The s aft 0 in turn is used for driving atamuch reduced rate the windin is transmitted rotates a'large pulley t onthe shaft t of the winding-drum. The drum or roller 70, which supply offelt, is a tension-roller. is provided with a brake-wheel a, upon whichis a brake-band i), one end and pro lvided with a weight w at the 0paper and the blocks, a rubber roller ac is rob the paper-F as thelatteris drawn d bythe drum H.

Preferably theidriving mec anisms are all arrangedupon one side of the machine,(see Fig. 3,) leaving the other side freelyaccessible to th .of the work at all tlmes and correction of it in themanner explained. The operator of course will stand on the side oppositethe mechanism.

With these parts of the machine asdescribed it is only necessary to modify slightly the mechanismfo'rconducting the blocks fromthe traysto the orizontal support. From eachof the trays the blocks are fed in continuous lines 'to the horizontaltable. akin 'a-set of theseutes in one vertical plane, b ocks will befed alternately from one or the other of the chutes y esoa ementdevices, so that in the line of asse'mb ed bloc corres ondin tothechutes in this vertical plane t e blodl s will be arranged in adetermined order.

er of arrangement of the blocksfor each of the lines bem determined, theentire pat tern is controllable at will. I I Referring to the mechanismof Figs. 8, 9', and 10 and theexample of Fig. 11, we su pose it tobedes'ired to make a section of tl ie utes 7, 8, and 9 will be provided,each fed y a separate tray or equivalent device and carrying,respectively, red, White, and blue blocks.

Above and 17, respectively, carryingtrips for opercarried on drums 19 .on t e severa shafts.

aking a series of pins 18 in'a vertical plane as, for example, the planeimmediately at the left of the 'center-.it'will be seen that there arepins in one or another for every one of the eight of the three drumsoints into which the circumference is. divide ,but no two pins he samepoint. Therefore for each anposition of the severalshafts-and it is pin18,, down the second plock mtheline and lifting each tr'ay is patternswith blocks of Thus the or- 7 too of the escapement 10, holding tableand cut into sections of suitable length,

l'laring the mouth of each chute to width earn the stop 11, so as topermit the escape of the first block, which runs quickly down until itstrikes the rearmost bloclr of those which are already assembled. Byvarying the positions of the pins 18 on the drums 19 the pet tern can beindefinitely varied.

The speed of the machine in practice is limited only by the capacity ofthe operator to correct the inaccuracies the blocks are fed along. Thelaying of the assembled sections can be accomplished very much fasterthan by the present metl'iod, which consists generally in throwing thebloc on the floor loosely and then by hand sh ring them into place twoor three at a time and simultaneously throwing out or turning overimperfect ones. Special patterns of colored blocks are usually made bylaying the blocks one by one upon a strip of adhesive paper in sectionstwo or three feet long and then transporting them to the job and layingthem as a unit. The making or" these units inv the shop requires skilledlabor and considerable time.

The composite stri s or units may be made by the machine of t iisinvention inv any de sired length to suit the floor to be laid. In steadof forming a roll of the composite strip upon the drum it may no fed outupon a flat thus avoiding the necessity of unrolling it and removing thefelt. (See Fig. 17, hcreinafter described.)

For making straightdine borders-that is to say, l rdcrs or patterns ofdifferentlycolored blocks in which the lines of one color run all in. alengthwise direction-it is not necessary to use escapement devices, butonly to food bloclis of desired colors into the chutes l) of Fig. 3,each chute carrying blocks of only one co or. The cscapomcnt d evicc or'9 may also be used to lay a plain field with a small figure at longintervals, as is dosirablc to break the monotony of a large blank space.For this purpose the set of chutes carrying the field-blocks would alonebe operated for a considerable distance, and the chutes containing thesupplementary colors would be brought into operation only at desiredintervals. In making keralnic the operator would have to turn thefinished or lac sides of the blocks up, and preferably the canvas mmvrryor E illustrated would be replaced by a bolt having depressions intowhich the blocks would lit, thus automatically breaking joints, as isusual in this class of work.

By a long series of efipcriinents l have found that the tendency of theblocks to wedge in the chutes I) may be corrected by equal to a littleless than twice the width of a block. lVith this arrangement when twoblocks strike the mouth of a chute simultae neously one is held back andthe other runs freely into and through the chute. con

struction is illustrated in-Figs. and 13, in which the chutes l) areprovided with flaring months 20 of slightly less width than the twoblocks 21 placed side .by side. in this arrangement the intermediatewalls or guides K may be, and preferably are,n1ade of uniform heightthroughout their length instead of being tapered, as illustrated inFigs. 7 and 7. The tray C is preferably provided with a spring 22 ateach side, which spriligs throw the blocks constantly toward the centerand correct the tendency to collect in the corners.

It is not essential that the intermediate support a and carrier ll]shall be interposed between the chutes and the roll upon which thecomposite fabric is wound. A much simpler machine may be made by cuttingout all the structure and mechanism between thp lower end of the chutesand the roller. For example, as shown in Fig. 14;, the blocks may passdown the chutis to the roller Hi, there being only a tray (1 between thelower ends of the chutes and the roller. This tray receives the blocksdirectly from the lower end of the chutes and in a loose condition andcompacts them in the same manner as the tray d of Fig. l. The tray ispreferably pivoted at 23 to permit its lower end to move outward as thesize 01 the roll of composite fabric upon the roller H increases. Thepaper l passes from the roll f, past the glue-pot G, and thence directlyto the final roller H. The ielt passes directly from the roller K to theroll ll.

The applying, oi the blocks to a continuous fabric is not essential tothe invention. The blocks may, for example, be applied directly upon thedoor. For this purpose the apparatus will be mounted on wheels. F orexample, as shown in Figs. 15 and 16, a truck 24 may carry a motor 25,which drives the ruck slowly in the direction of the arrow and which atthe same time by means of a crank connection 26 jogglcs the tray 0 andkeeps the chutes D supplied with blocks, which run. down into a tray D,which receives them loosely and compacts them and "feeds them. out tothe rear the apparatus moves forward. The truck carries a hopper A witha valve U, which may be operated autbmatically or by hand by anattendant who works alongside of the apparatus. Fig. 16 illus trates afloor upon which u e complete line of mosaic has been laid adjacent tothe wall. and the next line is being laid by the machino. The machineillustrated is not constructed to-work in corners or along the marginsof walls, though it n'iight obviously be modified to feed at-the sideinstead of at the center, as shown.

This specific machine is not claimed herein but it is not to beunderstood that I thereby waive my right to claim the same in a separateapplications In order to form a composite 'iabric straight lengthsinstead of upon a roll, the paper and the blocks may be fed upon a longendless belt in the manner indicated in Fig. 17. The blocks come downchutes D, as before described, into a tray D, the chutes and tray beingof sufficient length to permit the removal of defective blocks. Theblocks are then inverted by forming a rqperly-curved end 27 upon thetray D and y Earranging an adjustable hood 0, as in Fig. .1, thehoodterminating in a chute or apron d which serves the same purpose astheapron d in Fig. 1 The paper is fed below the lower end of the chute dand receives the blocks directly upon its adhesive face, and from thispoint the composite fabric is carried along on an endless belt 28 andcut off in suitable lengths. The inversion of the blocksserves thedouble purpose of exposing for inspection in the tray.

those faces of the blocks which are to form the surface of the floor thefinished fabric in a backward direction under the mechanism for feedingthe blocks, thus compacting the machine considerably The weight of theblocks is sullicient to cause them to adhere to the paper and to givethe latter a good grip upon the belt. The blocks of course may be of anysuitableshape, circular or polygonal.

's specific mechanism for forming the fabric in straight lengths is notclaimed in the present application, it being understood,

owever, that I do not thereby waive my right to claim the same in aseparate application. i

The lines of blocks are in substantial contact with each other-that isto say, for ordinary mosaic with rough side faces the contact is atseparate points, so as to leave the usual space for cement betweenadjacent blocks, while for regularly-molded blocks, as so-calledceramic, there would be a slight space, a sixteenth of an inch maximum,for the cement but there would be no dividing-partitions or the likebetween the blocks as they are fed out of the machine.

Though I have described with great particularity of detail certainembodiments of the invention, yet it is not to be understood that theinvention is limited to the specific embodiments disclosed.
